What size propeller is required to lift a 180 lb person 30ft into the air consistently? Also, how powerful would the motor have to be to lift itself, the propeller, and person?

Not quite. I am looking for a 2 bladed prop. This is a theoretical question at this stage.

I think you can google "static thrust calculator" and find what size of propellers and motors are available.

From the Wikipedia page on mechanics of helicopter flight:
For stationary flight, out of ground effect, and for a helicopter weight F
where
is the air density.
The induced velocity needed for lift will be:
and the power (called induced power) :
.
For example, in the case of a small helicopter of 700 kg mass and a rotor diameter of 7 m:
= 60 kW = 80 hp
